荧光定量PCR对微小RNA的检测及应用

目的:建立一种定量、简单、快速、敏感的微小RNA(miRNA,miR)检测方法,并用其观察一些病理状态下有关miRNA的变化.方法:通过特殊设计的茎环结构的反转录引物,对miRNA进行反转录,然后用相应miRNA的正反向引物对该miRNA进行定量检测,观察重复性和特异性.用此法检测了人巨细胞病毒(HCMV)对滋养细胞(HPT-8)细胞内miR-513表达水平的影响,也检测了结直肠癌组织miR-145水平.结果:用该法扩增miRNA特异性强,结果重复性好,该法检测到HCMV感染对miR-513表达的梯度效应.也发现癌组织和正常组织间miR-145的表达有明显的差异.结论:用荧光定量PCR可以对微小RNA快速有效的检测,在临床工作中可得到很好的应用.     

Effects of single‐case reading interventions for students with and at‐risk of emotional and behavioral disorders in grades K–12: A quantitative synthesis

This study examined the effects of reading interventions from single‐case design studies for students with and at‐risk of emotional and behavioral disorders in grades K–12 using a quantitative synthesis. Seventeen studies met the selection criteria of having one more dependent variables meeting what works clearinghouse (WWC) design standards with or without reservations. Although students’ reading performance significantly improved from baseline to intervention phases (p < 0.001), the overall weighted average effect size was weak (Tau‐U = 0.58, 95% confidence interval = [0.54, 0.63]; d = 0.29); smaller effects were found on reading comprehension. Interventions were less effective for students in secondary grades, students with a comorbid disability, and students in substantially separate settings. While no studies meeting the selection criteria were conducted in inclusive settings, the teacher provided interventions were more effective than those provided by researchers suggesting the importance of the student–teacher relationship for reading instruction. Study limitations, areas for future research, and implications for school practices are discussed.     

Improving Writing Skills of Thai EFL Students by Recognition of and Compensation for Factors of L 1 to L2 Negative Transfer

In this study, we examined the likelihood of a TAME （extended technology acceptance model）, in which the interrelationships among computer self-efficacy, perceived usefulness, intention to use and self-reported use of computer-mediated technology were tested. In addition, the gender- and age-invariant of its causal structure were evaluated. The data were collected from a self-reported questionnaire administered to 477 administrative staff of a public university in Malaysia. The results of structural equation modeling supported the adequacy of TAME. Although the TAME＇s causal structure was applicable to both male and female staff, age group appeared to moderate the structural relationships among the constructs of interest.
